Abstract: In a driving system, first and second inverters are connected to a driving motor, one end of a stator winding through which 3-phase current flows is connected to an output line of the first inverter, and the other end of the stator winding is connected to an output line of the second inverter. A winding pattern of the driving motor includes: coils wound in slots defined in the stator and to which 3-phase current is applied; coils wound on innermost and outermost sides based on a direction toward a rotating shaft of the driving motor in the slots, and being energized by different AC phases; and coils disposed between a first coil located on the outermost side and a second coil located on the innermost side, and being energized by the same AC phases as those of the first and second coils.

Abstract: An integrated circuit device includes a fin-type active region protruding from a top surface of a substrate and extending in a first direction parallel to the top surface of the substrate, a gate structure intersecting with the fin-type active region and extending on the substrate in a second direction perpendicular to the first direction, a source/drain region on a first side of the gate structure, a first contact structure on the source/drain region, and a contact capping layer on the first contact structure. A top surface of the first contact structure has a first width in the first direction, a bottom surface of the contact capping layer has a second width greater than the first width stated above in the first direction, and the contact capping layer includes a protruding portion extending outward from a sidewall of the first contact structure.

Abstract: A laundry apparatus is disclosed. A laundry apparatus includes a cabinet, a drum rotatable in the cabinet, a weight balancer compensating eccentric rotation of the drum, and a securing member inertedly securing the weight balancer to the drum.

Abstract: An integrated circuit (IC) device is provided. The IC device includes a detector configured to detect an abnormal condition of the IC device and to generate a detection result as an attack signal, and a noise filter configured to filter out the attack signal as noise and to generate a filtered attack signal. The noise filter is configured to filter out the attack signal as noise when the attack signal is not maintained at a first logic level for a reference period and to generate the filtered attack signal when the attack signal is maintained at the first logic level for the reference period.
